Slingo Reel King Pros and Cons

Playing Slingo Reel King has some advantages and disadvantages. Below are some points we have highlighted to help decide whether this game is for you or not:


  • Action-packed and entertaining.
  • Has a big bonus game and other great features.
  • Fully optimised for mobile and desktop.
  • A unique and modern theme.


  • It lacks a gamble feature.
  • May not be appealing to all.

Slingo Reel King Theme and Design

Slingo Reel King game has a unique theme and an appealing design. The developers have combined traditional slot games and the classic 75-ball bingo game. Once the game screen has come on, you will see a royal blue background with a velvet-like outlook. Unlike standard online slots with the Spin button at the centre, it is located on the right side.

Each ball in the game reveals a set of five numbers that are displayed in the golden frame with white lines at the bottom of the reels. There is a visual display of game lines and the payouts they offer. Additionally, there is background music that's added to the classic atmosphere.

Overall, Sling Reel King has an intuitive design backed by crisp graphics and excellent sound effects.

Slingo Reel King Features

One thing you will like about this game is that it comes with incredible features to boost your chances of winning. The features you expect to come across in this game are:

Reel King Bonus Trail

The Reel King Bonus Trail feature determines how many symbols will show up on your grid during the bonus and the cash prize you stand to win. Each reel can randomly 'ding' on any spin to highlight a section of the slot reel and light up an arrow on the Reel King trail.

Reel King Bonus

The first stage of the Reel King Bonus is triggered when 5 'dings' occur. When this happens, you can be sure to get some decent payouts. Getting 9 'dings' will award the highest bonus prize of the Ultra King. Additionally, there are several reel king symbols that will appear and spin towards the prizes. But it depends on which stage of the bonus is triggered.

  • Reel King: 1 to 3 symbols
  • Great King: 2 to 4 symbols
  • Super King: 3 to 5 symbols
  • Mega King: 4 to 6 symbols
  • Ultra King: 7 to 9 symbols

Furthermore, each level has increasingly valuable reels, and each symbol spins to return prizes based on the following paytable:

  • 3x Red 7s pays 5x
  • 3 Yellow 7s pays 2x
  • 3x Blue 7s pays 1x
  • 3x mixed 7s pays 0.4x

Please note that the bonus will be active until no more wins are generated. Players are awarded the cumulative win amount from the streak.

Extra Spins Feature

There are extra spins after each game, and the price of each spin depends on the grid position and the potential prizes. Players can regulate the number of extra spins and the maximum prizes. The more extra spins you buy, the more chances you have of activating the captivate-king bonus.

Slingo Reel King Slot Symbols

The symbols used in Slingo Reel King are not the usual ones you can find in a standard online slot machine. As the 'ding' sounds get into your head, you will notice some familiar features in the game. These symbols include:

  • Wild Symbol: It gives you the opportunity to mark any number in the column above the reel position.
  • Super Wilds Symbol: It enables you to mark any number within the entire grid position in the main game.
  • Free Spins Symbol: This symbol grants a Free Spin and thus, increasing your playing time.
  • Blocker Symbol: This symbol prevents the potential number of matches on the grid.

Slingo Reel King RTP, Variance and Bet Limits

The theoretical payout (RTP) in Slingo Reel King is capped at 95%, which is the average industry standard. Additionally, this slot has a variance ranging between low and medium. This means that low wins can be obtained more regularly than big wins, with a wide betting range of between a minimum of 20p and a maximum stake of £25. Thus, Slingo Reel King is suitable for players of all budgets.

Steps To Play Slingo Reel King

The good thing about this game is that the gameplay works in the same way as the classic Slingo games. The objective is to match numbers on the game grid with the numbers that land on the reel.
